مقدمه: با توجه به سهولت دستیابی به سلول های بنیادی حاصل از بافت چربی نسبت به سایر منابع سلول های بنیادی در صورتی که بتوان از عوامل رشد مانند استروژن جهت افزایش تمایز نرونی استفاده نمود، نرون های تمایز یافته، در پیوند اتولوگ بیماری های عصبی دژنراتیو خاص مانند بیماری پارکینسون و ضایعات نخاعی استفاده ی وسیعی دارد. هدف از این مطالعه، ارزیابی تأثیر استروژن بر تمایز عصبی سلول های بنیادی مشتق از بافت ...
vaccines is considered as a critical point and in-process of quality control (ipqc) test of vaccine production. rapid tests, like real time pcr, are more appropriated when the production occurs at industrial scale because of the amounts of starting materials and the excess of consumed time required. in the current study, a real-time quantitative reverse transcription-polymerase chain reaction (...
conclusions our study demonstrated that a low dose of rmp could inhibit hbv transcription and replication, which is dependent on the appearance of hbx in vivo. results rpb5-mediating protein could inhibit hbv transcription and replication in groups transfected with the 1.2 wt and hbx. the inhibitory effect disappeared in the 1.2x (-) groups, yet it reappeared in the groups co-transfected with 1...
Adult neurogenesis is a process of producing nerve cells from their progenitor that occurs in some areas in the brain such as the hypothalamus. Low activity in this area plays a role in neural degeneration and diseases such as multiple sclerosis, epilepsy and depression. MS is a neurodegenerative disease with a permanent disability that the main reason for it is axonal degeneration and neuronal...
Introduction: Breast cancer is the most common malignancy in the female population and is the leading cause of death. Surgery, chemotherapy, radiotherapy, and monoclonal antibody (trastuzumab) therapy are common and standard treatments for this cancer. However, there are significant limitations in the treatment of this disease by using regular methods. Given the role of transcription factors (T...

this study was done to gain insights into transcriptional regulation of negative energy balance (neb) assoctiated genes. overexpressed genes in neb were identified using microarray and rna-seq data and promoter analysis of these overexpressed genes was applied to identify novel transcription factors. moreever, string database was used to construct a regulatory network of identified transcriptio...
Background: Sunflower (Helianthus annuus L.) is one of the important vegetable oil supplies in the world and in Iran, as well. It is classified as a drought semi-tolerant crop; however, its yield is adversely affected by drought stress. Understanding the initial events in sensing stress and the related physiologic and biochemical events thereafter, is crucial in designing droug...
SExtended Abstract Introduction and Objective: Small grain cereals such as wheat, are affected by types of destructive environmental factors such as abiotic and biotic stresses that severely reduce crop yields. To cope with these conditions, transcription factors cause plant resistance to these stresses by activating or suppressing the expression of genes involved in the resistance responses....
